OIL-BURNER.

Specification of Letters Patent.

Patented June 22, 1909.

Application filed June 16, 1908. Serial No. 438,746.

To all whom it may concern.'

Be it known that 1, XifrNrrnLD S. ROBIN- SON, a citizen of the United States, and a resident of Fresno, in the county of Fresno and State of California, have invented a new and Improved Oil-Burner, of which the 'following is a full, clear, and exact description.

This invention relates to certain improvements in oil burners adapted for use in cooking stoves, heating stoves, or for any and all other purposes where oil is used as a 'fuel 'for generating heat.

The special object of the invention is to provide improved means for vaporizing the oil and improved means for controlling the draft of air to the burner. l Reference is to be had to the accompanying drawings, forming a p art of this specification, in which similar characters ei' reference indicate corresponding parts in all the 'iigures, and in which- Figure 1 is a vertical section through a portion o'f a stove provided with a burner embodying my invention, said section being taken on the line 1-1 of Fig. 2, Fig. 2 is a transverse section on the line 2 2 of Fig. 1, and showing a top plan view of the burner; Fig. 3 is an end view of the burner; and Fig. 4 is a vertical section on the line 4-4 of Fig. 1.

In the drawings there is shown one ferm which my improved burner may assume, and the burner is illustrated in connection with a heating and cooking stove. The stove proper forms no portion of my invention and is illustrated only to set forth more clearly `the advantages and use of the burner.

The stove illustrated includes an outer' wall or casing 10, closed at the upper end by a top Wall 10, which latter may have apertures therein normally closed by the ordinary covers 11. TWithin the outer wall or casing 10 and beneath the top thereof, there is provided a lining 12 of insulating material, provided with a recess or chamber open at the top and at one end and serving to receive my improved burner. The burner illustrated is provided with oppositely-disposed substantially parallel side walls 13, 13, connected at their inner end by an end wall 14 and connected at their opposite or outer end by a face plate 15. The Aface plate extends out laterally beyond the side walls and is adapted to engage with the outer surface of the stove casing 10 when the burner is slid through an aperture in the latter, into the recess or chamber within the insulating lining above referred to.

The bottom of the burner is formed by a substantially horizontal flooring 16, extending from a point intermediate the ends of the burner to the rear end thereof, and by an inclined Vlloor section 17 extendingl from the substantially horizontal floor section 16 to the face plate 15 or front end of the burner. The face plate is provided with an aperture or opening 18 above the inclined floor section 17, and said loor section extends downwardly from the opening to the horizontal loor section 16. The floor section 16 is provided with a groove or channel 19 extending longitiulinally thereof, and the upper surface of the floor section may, if desired, be inclined downwardly to moet the groove. An oil delivery pipe 26 extends through the face plate 15 and through the inclined lloor section 17 and terminates adjacent the end of the groove whereby the oil or other liquid fuel delivered through said pipe will flow into the groove and distribute itself along the length thereof.

The top of the burner is partially closed by a cover plate 21, movable vertically between the side walls 13, 13, and at its rear end resting upon the rear wall 111. Pivoted between the side walls adjacent their front end, a plate 22 constituting a draft regulator, inclined downwardly to a point adjacent the end of the oil pipe 20 and the inner end of the inclined iloor section 17. The front end of the top or cover plate 21 rests upon the plate 22 adjacent the free end thereof, and means are provided for raising and lowering the inner end of the plate 22 to vary the inclination of said plate and also vary the inclination of the cover plate 21. Said means preferably comprises an eccentric 23 mounted on suitable journals in the walls of the burner and having an operating handle 24 outside of the stove for rotating the same. The cover plate 21 is provided with a suitable opening 25 therein, through which the flames of the burner may pass. The particular shape or form of the opening may be varied, depending upon the particular use for which the burner is to be employed, but the opening as shown, is in the forni of a slot extending longitudinally of the plate and above the groove 19.

ln the operation of my improved burner,

the oil or other liquid fuel, is admitted through the pipe 20 and collects in the groove A19. Air is admitted through the opening 18 and passes beneath the lower edge of the draft regulator 22 to the oil. The flames issue through the opening 25 and are directed toward the object or article to be heated. By rotating the eccentric 23, the position of the draft regulator 22 may be varied to admit a greater or less quantity of air through the passage between the inner end of the draft regulator, and the lower end of the inclined floor section 17. rlhe raising or lowering of the draft regulator is accompanied by a corresponding raising or lowering of the plate 2l to vary the size of the combustion chamber and accommodate the device to the increased or decreased rate of combustion resulting from the varying of the draft. a

Having thus described my invention, I claim as new and desire to secure by Letters Patent:

l. A burner having a combustion chamber, the top of which is formed by a substantially horizontal apertured plate, a draft controller comprising a movable plate having one end thereof extending into said combustion chamber and beneath said first-mentioned plate, and means for simultaneously raising or lowering each of said plate 2. A burner having a combustion chamber, the top of which is formed by a substantially horizontal apertured plate, a draft controller comprising a plate pivoted at one end thereof and having the other end extending into said combustion chamber and serving to support one end of said apertured plate, and means for swinging said draftecontrolling plate upon its pivot.

3. A burner having a combustion chamber, the top of which is formed by a substantially horizontal apertured plate, a draft controller comprising a plate pivoted at one end thereof and having the other end extending into said combustion chamber and serving to support one end of said apertured plate, and an eccentric in engagement with the under surface of said draft controllingplate for swinging it upon its pivot.

Al. A burner having oppositely-disposed substantially parallel walls, a. bottom wall having a substantially horizontal section provided with a longitudinally disposed groove and a downwardly-inclined section, means for delivering oil adjacent the intersection of said bottom Wall sections and adjacent one end of said groove, a face plate at the upper end of said inclined wall section and having an air inlet, a draft-controlling plate pivoted adjacent the upper side of said air inlet and having the free edge thereof adjacent the intersection of the bottom wall sections, means for swinging said draft-controlling plate upon its pivot, and an apertured cover plate having the rear end thereof supported substantially stationary and having the opposite end thereof supported upon said draft-controlling plate.

ln testimony whereof l have signed my name to this specification in the presence of' two subscribing witnesses.
